Influence of Rotational Nucleosome Positioning on Transcription Start Site Selection in Animal Promoters

Giovanna Ambrosini, Philipp Bucher, René Dreos

The recruitment of RNA-Pol-II to the transcription start site (TSS) is an important step in gene regulation in all organisms. Core promoter elements (CPE) are conserved sequence motifs that guide Pol-II to the TSS by interacting with specific transcription ...

Single Molecule Localization and Discrimination of DNA–Protein Complexes by Controlled Translocation Through Nanocapillaries

Aleksandra Radenovic, Sebastian Maerkl, Sanjin Marion, Roman Bulushev, Sebastian James Davis, Ekaterina Emilova Petrova

Through the use of optical tweezers we performed controlled translocations of DNA-protein complexes through nanocapillaries. We used RNA polymerase (RNAP) with two binding sites on a 7.2 kbp DNA fragment and a dCas9 protein tailored to have five binding si ...

Detection of Convergent Genome-Wide Signals of Adaptation to Tropical Forests in Humans

Matthieu Foll

Tropical forests are believed to be very harsh environments for human life. It is unclear whether human beings would have ever subsisted in those environments without external resources. It is therefore possible that humans have developed recent biological ...

Upstream Binding of Idling RNA Polymerase Modulates Transcription Initiation from a Nearby Promoter

Giovanni Dietler, Aleksandre Japaridze

The bacterial gene regulatory regions often demonstrate distinctly organized arrays of RNA polymerase binding sites of illdefined function. Previously we observed a module of closely spaced polymerase binding sites upstream of the canonical promoter of the ...

A large-scale, in vivo transcription factor screen defines bivalent chromatin as a key property of regulatory factors mediating Drosophila wing development

Bart Deplancke, Monica Albarca Aguilera

Transcription factors (TFs) are key regulators of cell fate. The estimated 755 genes that encode DNA binding domain-containing proteins comprise similar to 5% of all Drosophila genes. However, the majority has remained uncharacterized so far due to the lac ...

Population Variation and Genetic Control of Modular Chromatin Architecture in Humans

Bart Deplancke, David Hacker, Gilles Udin, Sebastian Martin Waszak, Sunil Kumar Raghav, Nouria Hernandez, Alisa Yurovsky, Sarah Thurnheer

Chromatin state variation at gene regulatory elements is abundant across individuals, yet we understand little about the genetic basis of this variability. Here, we profiled several histone modifications, the transcription factor (TF) PU.1, RNA polymerase ...

Relevance of the Drag Force during Controlled Translocation of a DNA–Protein Complex through a Glass Nanocapillary

Aleksandra Radenovic, Sanjin Marion, Roman Bulushev

Combination of glass nanocapillaries with optical tweezers allowed us to detect DNA-protein complexes in physiological conditions. In this system, a protein bound to DNA is characterized by a simultaneous change of the force and ionic current signals from ...

Noise analysis of genome-scale protein synthesis using a discrete computational model of translation

Vassily Hatzimanikatis, Julien Racle, Adam Stefaniuk

Noise in genetic networks has been the subject of extensive experimental and computational studies. However, very few of these studies have considered noise properties using mechanistic models that account for the discrete movement of ribosomes and RNA pol ...
